Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:

Nine cars we wish were convertibles

The snow has melted, the sun is shining, and the days are getting longer. At the Autoblog Detroit office we feel like our winter hibernation is finally over. And with warmer temperatures come visions of opening up a convertible roof and cruising. You know, just turn up the bass and let the Alpine blast. There are plenty of droptops on sale in the US, and more on the way (like the 2016 Mazda MX-5 Miata). That said, we always want more. More! More! More! In that spirit, we cooked up a list of nine cars aren't currently sold as convertible, but ought to be. Check out our picks, below. Summer's just around the corner. Subaru BRZ / Scion FR-S In some parallel universe, this car actually happened. Toyota showed us a FT 86 Convertible concept at the Geneva Motor Show in 2013, and we immediately started licking our chops over the thought of a rear-wheel-drive convertible based on the Subaru BRZ and Scion FR-S twins. These days, the MX-5 Miata is our only option for affordable roadster fun. A competitor to the Mazda seems like a no-brainer to us, especially since we have naught but good to say about the BRZ/FR-S as-is. Unfortunately in our present timeline, this car is as likely for production as a BRZ STI. Which is to say, not very. Dang. Lexus RC F Unlike the FR-S, a convertible from Toyota's luxury division might actually see the light of day. The current IS convertible is about to be phased out, and the Lexus LF-C2 concept from the 2014 Los Angeles Auto Show is really a thinly veiled look at a possible RC convertible. A droptop RC would be plenty good, but let's reach for the starts. What we really want is to run topless in an RC F, complete with that powerful, loud, 5.0-liter V8 engine. Lexus says the RC F is a true competitor to the BMW M4. If that's true, it only makes sense for Lexus to mimic the Germans and offer its performance coupe in a folding hardtop form. Maybach Landaulet Maybach is bach back, recast as an upper crust trim level for Mercedes-Benz. The Mercedes-Maybach S600 is seriously awesome, and more luxurious than a trip to the spa. But why not go a step into the truly ridiculous levels of extravagence and bring back that open-top Landaulet? We think your local princess will love this idea, and with better S-Class bones underneath, Jeeves will have a pretty enjoyable ship to steer, too. Besides, with that slick new Mercedes design language, a Landaulet redux wouldn't be nearly as hideous as the old model, pictured here.

Trump tells Detroit 3 CEOs he wants more US jobs, calls environmentalists 'out of control'

As expected, President Donald J. Trump met with top executives from FCA, Ford, and General Motors this morning as part of a larger push to generate jobs in America. "I want new plants to be built here for cars sold here!", Trump said in a tweet ahead of the meeting. Not everything said in the meeting was made public, but the President later tweeted that he had a "Great meeting with automobile industry leaders." FCA CEO Sergio Marchionne, Ford chief Mark Fields, and GM's Mary Barra all echoed the positive vibes after the meeting. In a statement, Barra called the discussion "very constructive and wide-ranging," adding that it focused on "policies that support a strong and competitive economy and auto industry," and "that supports the environment and safety." That's noteworthy, because Trump is reported to have said "I am to a large extent an environmentalist. I believe in it, but it's out of control." Fields, speaking to reporters after the meeting, said, "We're excited about working together with the president and his administration on tax policies, on regulation and on trade to really create a renaissance in American manufacturing." The Ford CEO was specifically talking about Trump's withdraw from the Trans-Pacific Partnership. "We've repeatedly said that the mother of all trade barriers is currency manipulation, and TPP failed in meaningfully dealing with that, and we appreciate the president's courage to walk away from a bad trade deal," he said. Marchionne focused on American manufacturing in his statement after the meeting. "I appreciate the President's focus on making the US a great place to do business. We look forward to working with President Trump and members of Congress to strengthen American manufacturing." Perhaps equally as interesting as what was said and who was invited are what wasn't said and who wasn't invited. Trump has been very vocal about his distaste for US automakers' plants in Mexico, but no mention was made of the North American Free Trade Agreement by Trump or any of the Detroit CEOs after the meeting. We also have to wonder if Trump plans to meet with representatives from German, Japanese, and Korean automakers that have made massive investments into American plants and produce a large number of cars in this country.
